Key Findings
- 01Participants became faster and more accurate over repeated collaborative interactions.
- 02Linguistic and gestural abstractions were established to represent procedural steps.
- 03Cross-modal redundancy (using both speech and gestures for emphasis) was employed to highlight significant changes from previous interactions.
Application
Design takeaway
Design collaborative tools that allow users to communicate using both speech and gestures, and consider how to leverage redundancy between these modalities to emphasize important information and facilitate the development of shared task abstractions.
How to apply
When designing collaborative software or hardware, consider incorporating features that allow users to communicate via voice, text, and visual cues (like drawing or pointing), and analyze how these modalities are used to convey information and build shared understanding.
Project actions
- 01Consider how users might naturally develop shorthand communication in your design project.
- 02Explore how to integrate different communication methods (e.g., voice, gestures, text) into your design.
- 03Think about how to highlight important information in a way that users will easily understand.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Investigated both unimodal and multimodal communication.
- +Used a combination of online and lab-based studies.
- +Developed a computational model to capture modality shifts.
Limitations
The specific task used in the study might not be representative of all collaborative work. The technology used (AR) might have influenced how participants communicated.
Reliability & validity
The study's validity is supported by the use of a controlled lab environment and objective measures of performance (time, accuracy). Reliability could be enhanced by replicating the study with a larger and more diverse sample, and by using standardized coding for gestural and linguistic abstractions.
Think critically
To what extent can intelligent systems be designed to proactively facilitate the formation of effective communication conventions, rather than simply adapting to user-generated ones?
Design Principles
"Embrace multimodal communication to foster emergent conventions and enhance collaborative efficiency."
Understanding how users naturally develop communication conventions is crucial for designing intuitive and efficient collaborative systems. By supporting both verbal and gestural input, designers can create interfaces that better mirror human interaction patterns, reducing cognitive load and improving user experience in shared tasks.
What This Means for Your Design
When people work together, they get better by developing their own secret codes using words and actions. This makes them faster and less likely to make mistakes.

Paragraph starter
This research highlights the power of multimodal communication in collaborative tasks, demonstrating that the combination of verbal and gestural input facilitates the formation of shared abstract conventions. By developing these conventions, collaborators achieve greater efficiency and accuracy, particularly when critical information is emphasized through cross-modal redundancy. This suggests that design projects aiming to enhance collaboration should consider integrating and supporting diverse communication channels to mirror natural human interaction patterns.
